This is my 3" (does not neck down) Helix stainless steel catback. Robot tig welded, thick flanges, and polished. Very nice!

3" B&B Downpipe
3" Perrin Testpipe with heatshields
3" Helix Catback

 

and my heatshields i got for my testpipe from prostreetonline.com

 

Looks really cool, my consensus is that it's going to sound very loud and deep. perfroamcen should make up for that though .

 

I'll add to this..

I got my 3" Helix Downpipe and Cat-Back from www.gruppe-s.com, but i'm sure www.prostreetonline.com would accomodate aswell. The midpipe does not neck down at the cat, 3" all the way. It will bolt up to stock or aftermarket cat. The downpipe clears the stock member braces without the use of spacers. It retains the use of the factory donut gasket and spring bolt hardware. I currently have it bolted to the stock cat and it is not that loud. The exhaust at idle is slightly louder with a deeper tone, but not excessively loud to bother my neighbors. The cat-back also comes with silencer for the muffler if needed. The tone is nice, does not drone during cruising and sounds really mean under WOT. The 4.5" tip exiting the muffler clears the bumper without leaving any soot. www.kartboy.com hangers add a nice touch and helps keep things in place.
